The word "叱吒" is formed from two characters, each constructed as a phonetic-semantic compound: "叱" combines the mouth radical (口) with the phonetic component "七" to denote shouting, while "吒" uses the mouth radical (口) with the phonetic component "乇" to signify roaring; together, they create a disyllabic word meaning to bellow or roar, emphasizing vocal force.
